audioDB::query_loop and audioDB::query_loop_points are no more.

Be a little bit careful about deleting the exact_evaluation_queue in
error conditions, but otherwise this was simple (If you ignore the work
of the previous $N$ commits, that is).  The inversion work in query.cpp
is now complete, apart from physically teasing apart the API function
from the body of audioDB::query and then moving the two remaining
audioDB:: methods elsewhere.  Unfortunately, we're still not quite done,
because we have to deal with audioDB::index_query_loop too, which is
still a little bit tangled.  Still, we're nearly there...
